TYPE-CASTING MACHINE.

Application filed December 13, 1912.

To all whom it may concern Be it known that I, O'rro G. SoHMrr'r, a subject of the German Empire, residing at Chicago, in the county of Cook andState of Illinois, have invented a certain new and useful Improvement in Type-Casting Machines, of which the following is a full, clear concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to a multiplex type casting machine and has as its principal object to increase the output and decrease the unit cost of existing type casting machines.

A. second object of my invention is to cast two type in each revolution or cycle of operation of the machine.

A third object is to increase the percentage of each revolution or cycle during which the type may remain in the mold.

A fourth object is to provide an improved means of operating the ram from a cam so as to increase its speed of movement.

A. fifth object is to provide means for varying the width or point of type cast by the machine.

A sixth object is to provide means whereby the type metal is prevented from freezing in passages connected with the mold, and from dripping into the mold.

A further object resides in the particular arrangement and combination of parts hereinafter described.

With these and other objects in view, my invention comprises a plurality of type molds, a matrix which may be used with first one mold and then the other, and means for forcing molten metal into first one and then the other of the type molds.

Referring to the accompanying drawings, which form part of thisspecification, Fig ure 1 is a front elevation of my machine, parts of the frame being shown in section and other parts of the frame being broken away; Fig. 2 is top plan view of Fig. 1;

Throughout said views the same part is referred to by the same reference characters.

Referring more particularly to the drawings, 1 is a casting in the 'form of a hori- Zontal plate, upon which my machine is supported. Suitable brackets not shown are provided for supporting the plate 1 from the floor.

2 is a frame supported on the plate 1 in parts of my machine are carried. As shown in Fig. 3 the frame 2 is set at an angle to the vertical for a reason to be mentioned later.

8 is a main driving shaft mountedbeneath the plate 1, on which are mounted the cams 4:, 5 and 6. Shaft 3 also carries a gear 7 which drives the shaft 8 through the gear 9. The shaft 8 is nearly vertical, as appears in Fig. 1 and carries at its upper end a cam 10. The cam 10 drives a reciprocating ram 11 by means of a removable pin 12 which has a sliding connection with the ram passing through a hole near the left end thereof as viewed in Fig. 1. The ram 11 is reciprocated in the guides in the frame 2 as clearly shown in Fig. 5. The combined action of the cam 10 and the pin 12 is such that the ram reciprocates first to the right and then to the left, and pauses or dwells at each end of its stroke. By mechanism to be described more in detail later, a type is cast during each pause or dwell of the ram at the ends .of its stroke, thus casting two type for each complete reciprocation of the ram or 1. A pin 17 passes through the upper end in F ig, 1; Assuming the ram to be at the of the pin 12 and slides in the slots 16 in the two forks 15. The lever 13. has a pin connection with the upper end of the vertical slide or checker rod 18, which is operated by means of the checker cam 6'shown right end ofa stroke, (Fig. 5) when the rod 18 moves downwardly the pin 12 isa, forced into the circular portion 19 of the groove shown in the upper face of the cam 10. The pin and ram are then moved to the left, while the pin 12 occupies the portion of the groove 20. As soon as the pin reaches the small circular portion 21, the rod 18 lifts upwardly and withdraws the pin 12 from the groove. The'ram has thus been removed from its right hand position to its left hand position, and the pin 12 has been moved from the right hand end of the slot 16 to'the left hand end. When now the rod 18 descends upon its next succeeding stroke, the pin 12 will be inserted in the cam groove in the circular portion 21, and the pin 12 will be moved to the right by the portion 22and the pin will be withdrawn when it strikes the circular portion 19, lea-ving the ram again in its right hand position. Now the cam 10 is geared so as to revolve thirteentimes as fast as the main shaft 3, while the movement of the ram from right to left occurs in ninety degrees of the cam 10. If we assume that sixteen degrees of arc is the least which can be used to give satisfactory operation of any cam of prac tical size, it will be seen that the ram is operated at least two times as fast as it could be if it were operated direct from a cam on the shaft 3. But since the time that the ty'pe'must remain in the mold is fixed, the quicker the movement of the ram and the greater proportion of the cycle which canbe used for casting, the faster the main shaft can be driven. I assume that by using the improved ram movement just described I am able to operate the main shaft at twice the R. P. M. heretofore employed. The lever 13 at the end opposite the pin 12 is provided with a sliding pin connection with a second vertical pin 23, as shown in Figs. 2 and 3. The pin 23 is tapered at its lower end so as to engage correspondingly shaped holes in the block 24 fixed to the top of the ram 11. I One of these holes appears at 25 -will not be described.

in Fig. 2, while the other is immediately under the pin 23 in Fig. 2. The lever 13 is timed so that the pin 23 is forced into one of the holes 25 whenever the ram dwells at the ends of its stroke. The ram is thus held firmly and made to register properly with the mold and other apparatus during the casting process. Immediately below the central part of the ram and carried by pertions of the frame 2 is a mold block 26, as best shown in Figs. 3, 4, and 6. The upper portion of the block 26 is of the same width as the central portion of the ram, while the lower portion of the mold block is of greater Ewidth than the ram, as clearly appears in Fig. 3.

It will be understood that in practice mold blocks are made in several parts, and are water cooled, but thls being well known,

To the right of its center block 26 is provided with a slot or groove 27, and at the left of its center with a second slot or groove 28. The type are cast alternately in slots 27 and 28. The bottoms of these grooves are closed by movable fingers 2929 which are carried at the upper ends of body There is a loose connection between the ,plungers 30 and the levers 31, so that the cam and the levers serve only to lift the plungers and fingers while their downward movement is caused by springs 3232. The plungers 30-30 are operated only when it is desired to force a type out of the slots 27 and 28, the throw of the slots in the cam 5 being such as to lift the upper ends of the fingers 29 level with the top of the block 26. The slots 27 and 28 are separated by a distance equal to the travel of the ram while their bottoms are closed by the fingers 29. The ram 11 is also provided with two slots or grooves occupied by plates or fingers 33 and 34. The grooves occupied by the plates 33 and 34 are twice as far apart as the grooves 27 and 28. The upper ends of the plates 33 and 34 are embraced by circular pins 35 and 36 which are slidably mounted in sockets descending from the top face of the ram. The upper ends of the pins 35 and 36 contact with adjustable screws 37 and 38 which are carried at the ends of a rock arm 39, which is pivoted at 40 to the face of the block 24. At each side of the mold or block 26 is a type-way 41. The type-ways 41 are spaced apart a distance equal to three times the travel of the ram. A matrix 42 is suspended below a block 43 which moves from right to left with the ram. If the casting that two type have been cast previously, one in each of the molds 27 and 28. The molten type metal will now be forced into the slot 27 by mechanism yet to be described. Any type which may have been cast previously in the slot 28 will be cooled. As shown in Fig. 4 the plate will be in register with the slot 28 when the machine is casting a type in slot 27, and the ram will be at the right hand end of its stroke. Immediately before the ram moves to the left the left body plunger is operated so that the left finger 29 pushes the now cooled type from the slot 28 into the lower part of the groove occupied by the plate 34. Such a. type is shown at 44 in Fig. 4. The plate 34 will thus be pushed up and by means of the finger 06 and rock arm 39 and connected devices, will push down the plate 33 forcing any type which may be in the groove occupied by plate 33 into the right hand type-way 41. The ram now moves to the left, bringing plate 34 and type 44 in register with the left type-way 41, and plate 33 in register with the slot 27. Meanwhile the finger 29 has been withdrawn the thickness of the type. Metal is now forced into the slot 28 and after a slight pause the right hand finger 29 is elevated, pushing the type from the slot 27 up into the ram groove beneath the plate 33 and forcing the type 44 into the left hand type-way 41. The ram now moves to the right again into the position shown in Fig. 4, whereupon this cycle of operation is repeated. When a type is being cast the top of the mold slot is covered by the central part of the ram.

As previously mentioned, the slots 27 and 28 in which the type are. cast are closed at the bottom by means of fingers 2929 which are carried at the upper ends of the plungers 30. It will be evident from inspection of Fig. 4 that the thickness of the typ -will depend upon the length of stroke of the fingers 29. Since these fingers are operated on the down stroke by means of springs such as 32, the length of their stroke may be adjusted so as to cast type of different thickness. To accomplish this I provide a threaded bolt 45 which is carried in sockets in the fixed blocks 46 and 47, which form part of the frame 2. Mounted on the bolt 45 is a large threaded square nut 48 which carries stops on its upper face. The plungers 30-30 have offset lugs 4949, each of which carries a stop adapted to contact with one of the stops on the nut 48. By adjusting the vertical position of the nut 48 on the bolt 45 the operator can determine the distance which the fingers 29 can descend on the down stroke and consequently can determine the thickness of the type. For operating the bolt 45 I provide a worm wheel 50 fixed to the lower portion of the bolt, and a worm 51 meshing with the wheel 50, The

worm 51 is carried by a plate 52, appearing in Fig. 1, and has at its outer end a hand wheel 53. The plate 52 carries a counting attachment which may be of any known type, and which is operated from the worm 1 tween the plates 56-56, which are fastened to the front face of the ram 11. One of the plates 56 carries a guide block 57 which has a pointed edge so as to engage a groove in the side of the block 43, as shown in Fig. 7, the other side of the block 43 being guided by the other plate 56, as shown in Fig. 5, and also by dotted lines in Fig. 7. In this way the block 43 is adapted to slide transversely of the ram 11, and at the same time be transported by the ram. The blocks 57 are held in place by suitable bolts a8. The matrix is held between two horizontal plates 59 and 60 appearing in Figs. 3, 6 and 7. The plate 59 is carried by a 'sleeve 61 which runs up through the block 43 and is held up against the adjusting screw (32 by means of the spring 63. The plate 60 is attached to a rod or bolt 64 which runs up through the sleeve 61, and is pressed upwardly by means of the spring 65. On the side toward the ram 11 the matrix 42 is held in alinement by two fingers 66 66 which depend from the inner face of the block 43 and are firmly fixed to the block. The matrix is pressed against the fingers 66 by means of a spring pressed finger 67 which is carried by a boss 68 at the inner end of the threaded bolt 69. The bolt 69 is carried within a hollow sleeve 70, a spring 71 being provided within the sleeve to force the bolt and linger in the direction of the matrix. the finger engages the matrix best shown in Fig. 8, the lower block 60 being cut away to permit the finger to reach the matrix. A hand wheel 7 2 is provided by which the bolt can be operated to withdraw the finger 67 1 from engagement with the matrix. The

sleeve and parts supported therebyare carried by a plate 73 which is attached to the front of the block 43 at one end. The plate 73 carries an adjustable screw or bolt 74 1'.

which is adapted to contact with the outer face of one of the plates 56 to limit the movement of the block 43 and the matrix toward the ram 11, and the mold block 26.

The screw 74 thus provides means whereby T The manner in which longitudinal position of the matrix is, however, determined by a block 7 5 which is supported by an arm 76 which depends fromthe lower face of the block 41-3. The position of the block 75 can be adjusted by the screw 7 7 which 'is carried by the vertical part of the arm 76. The movement of the block 43 in the guides 57, andconsequently the'movement of the matrix toward and away from the molds is'effected by means of a lever arm 78 which appears in Figs. 1, 3 and 5. This arm 78 depends from a hub 79 which is splined on a shaft 80 carried by lugs 8181 on the front face of the frame 2. The hub 79 thus is enabled to slide longitudinally of the shaft 80. The shaft 80 is rocked in the lugs 81 by means of a lever 82 appearing in Figs. 1 and 2, which extends horizontally from its connection withtheshaft 80 to engage the vertical plunger or chocker rod 18 previously mentioned. It will be apparent from the relation shown in the drawing, that when the rod18 rises to withdraw the pin 12 from the cam groove in the cam 10, and to fix the position of the ram by forcing down the pin 23, that at the same time the block 13 by the connections just described, will be forced toward the face of the ram. The matrix 42 will thus be brought over one of the slots in the mold. W'hen, however, the rod 18 de scends so as to throw the pin 12 into the cam. groove in order to move the ram the block 43 will be moved from the face of the ram, and the matrix removed from contact with the mold, so that it may be transferred to the other mold slot without interference. Since fingers 66 project inwardly 'or rear wardly from the inside or back face of the matrix the front face of the ram is provided with two grooves such as S3 to receive the fingers. The fingers are shown in the position occupying these grooves in Fig. 5, and are shown moved away from the grooves in Fig. 6. The ram is provided with only two large grooves since the fingers travel with the ram and do not change their position longitudinally thereof, but the mold block 26 is provided with two pairs of smaller grooves such as 84 8f, and S5-85, appearing in Fig. 4, to receive the ends of the fingers.

As previously mentioned type metal is forced into the slots 27 and 28 at proper intervals to form the type. The pumping operation is controlled from the cam 4 on the shaft 3. Cam 4: operates a lever 86, best shown in Fig. 11. Lever 85 drives in turn the rod 87 which connects at its upper end with a lever 68 which is pivoted at 89. As shown in Fig. 11 the operation of the cam 1 is such as to lift the rod 87 only, while the down stroke of the lever 88 and the rod 87 is controlled by a spring 90. As shown in Fig. 3 the lever 88 passes through a yoke 91 which is connected to a pump plunger 92.

The plunger 92 reciprocates in a cylinder 93 which projects from the bottom of a metal pot 94. The cylinder 93 is provided with a chamber beneath the plunger 92, and is also provided with passages 90, through which the molten metal may flow from the pct 94 into the chamber 95 when the plunger 92 is raised. As shown in Fig. 11, the cam & is designed to lift the lever 88 twice during each revolution so as to give two pump strokes per revolution of the shaft The interior of the pot 94: is provided with a web 97 through which a passage is provided leading from the chamber 95 to a valve chamber 98. Consequently whenever the plunger 92 is depressed by the action of the spring 90 the metal is forced into the chamber98. Two nipple outlets 99 and 100 lead from the chamber 98 to mold slots 27 and 28 respectively. The connection of chamber 98 and the outlets to the mold slots are controlled by two similar valves such as 101. The valves 101 are carried on stems 102 which connect with vertical blocks 103 103. The upper end of each block 103 connects with a second stem 101: which is parallel with stem 102, both sets of stems 102 and 10st being guided in the sides of the pot 91. On the end toward the ram 11 the stems 101- are provided with enlarged heads 105 which reciprocate in sockets in the wall of the pot 9% and are normally pressed toward the ram by springs such as 106. By the connection between the stems 104 and 102 the spring 100 thus serves to hold the valves 101 normally closed. However, when the block 41 is pressed against the face of the rain on the opposite side thereof from the heads 105, a bolt 107 carried in the rain 11 is pressed by the block +13 against one of the heads 105 so as to open the valve 101 which controls the nipple outlet leading to the particular slot which 'is then corered by the matrix 1-2. When the matrix block moves away from the face of the ram the spring immediately closes the outlet. lVhen the ram and matrix block move into the position to cast a type in the other mold slot, the bolt is thereby carried into position to operate the other valve 101. It will be understood the type are only of the length equal to the width of the plates 33. This length is indicated in Figs. 3 and 5. The rear portion of the mold slots is accordingly made tapered as indicated also in Fig. The rear portion of the finger-s29 is consequently made of somewhat wedge shaped cross section which produces an edge 108. as shown in Fig. 3. It will be understood that the mold block being water cooled the type metal will solidify along the whole length of the mold slot,

- and consequently that a wedge shaped spur or jet will be cast on the rear end of the type. When the type are pushed up out of the mold slots by the fingers 29 these spurs are received in recesses 109 in the rear edge of the ram 11 appearing in Figs. Sand 6. Suitable knives (not shown) are fixed to the frame of the machine to break off these spurs and trim the rear end of the type while the type are being transferred by the ram from one of the mold slots to the typeway ll. Other knives such as 110ll0 and l1l111 are provided for trimming the other faces of the type, while it is being moved after having been cast.

The metal pot 94 previously mentioned is carried on a casting 112 which is mounted above the base plate 1, and carries a suitable burner 1.13 for keeping the type metal in a molten condition. Fastened'to ,the upper edge of the metal pot 94 is also a bridge shaped casting 113 in the horizontal portion of which is slidably mounted a rod 114 which connects with the top of the yoke 91. The upper end of the rod llfl carriesnuts against which a spring 115 is adapted to act in order to take up lost motion between the lever 88 and the yoke 91. It has been previously mentioned that the frame 2 is set at an angle to the vertical. This causes the mold slots such as 27 and 28 to incline to the rear and enables the nipples 99 and 100 also to be placed on an inclinationso that the metal will drain back out of the nipples into the chamber 98 as soon as the plunger 92 lifts and before the valve 101 is closed.

This prevents all danger of the metal freezing in the nipples, and also avoids danger of the metal dripping into the mold.

Referring to Figs. 9 and 9, which indicate diagrammatically the movements of my machine and comparing these movements with those shown diagrammatically in Fig. 9*, it will beseen that the matrix remains in contact with the mold during each casting operation for a greater part of each revolution, or cycle, than is the case in the old machine, although two type are cast from one matrix per revolution instead of one.

Also it will be seen that each type remainschocker cam performs the functions of both the checker and matrix,cam, thus eliminating one cam, that the pump cam operates twice in each revolution instead of once, that the dressing cam is omitted, that the body plunger cam operates twice in each revolution instead of once, and that the period of movgm t f e shortened. v 1 W 1 be und tood by those skilled i the art that various changes and modifications may be made in the device shown and described herein without departing from the spirit of my invention, and that I contemplate all such modifications and rearrangements as are mechanically the equivalent of the device shown and described herein.
